Summary
This study developed poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV)/bacterial cellulose (BC) biocomposites for biomedical use. These materials show improved cytocompatibility and controlled degradation, making them suitable for medical devices.
Area of Science:
- Biomaterials Science
- Polymer Science
- Tissue Engineering
Background:
- Poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) is a biodegradable polyester with potential for biomedical applications.
- Bacterial cellulose (BC) is a natural polymer known for its biocompatibility and mechanical properties.
- Combining PHBV and BC can create novel biocomposites with enhanced characteristics for medical use.
Purpose of the Study:
- To synthesize and characterize PHBV/BC biocomposites using melt processing.
- To evaluate the influence of BC on the melt processing, surface roughness, and degradation behavior of PHBV.
- To assess the cytocompatibility of the developed biocomposites using NCTC fibroblasts for biomedical applications.
Main Methods:
- Melt processing technique was employed to fabricate PHBV/BC biocomposites.
- Surface roughness was analyzed, and degradation rates were measured in phosphate buffer saline (PBS).
- Differential scanning calorimetry (DSC) and attenuated total reflectance-Fourier transformed infrared spectrometry (ATR-FTIR) were used for thermal and structural analysis.
- Cell viability, morphology, cell cycle, and collagen content were investigated using murine NCTC fibroblasts.
Main Results:
- The addition of BC to the PHBV matrix facilitated adequate melt processing and increased surface roughness.
- PHBV/BC biocomposites exhibited favorable long-term degradation profiles in PBS.
- Enhanced cytocompatibility was observed, with stimulated cell proliferation and extracellular matrix (collagen) secretion by NCTC fibroblasts.
- Thermal and structural analyses confirmed changes upon BC incorporation.
Conclusions:
- PHBV/BC biocomposites demonstrate promising properties for biomedical applications.
- The incorporation of BC improves the processability and surface characteristics of PHBV.
- These biocomposites support cell growth and collagen production, indicating good biocompatibility.
- The controlled degradation behavior makes them suitable for designing advanced medical devices.
